The new dam at Sycamore Pool in Bidwell Park’s One-Mile Recreation Area has been completed. The city can mechanically raise the dam in the summer to create the pool, meaning weekly cleanings will be much easier. The dam will also give the city the ability to manipulate the pool so it can be full in April and May to enhance the migration of spring-run Chinook salmon. Here, Ken Piercy, an employee of Thomas H. Williams Construction, walks around the dam while it is in the lowered position Tuesday.
